Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper presents calculation results on plasma ignition and combustion of coal in the furnace of the PK-39-II boiler at Reftinskaya SDPP. For mathematical modeling of coal combustion in the boiler furnace, a three-dimensional mathematical model Cinar ICE and a software package for physical modeling and calculation of hydrodynamics, heat and mass transfer and combustion of fuels in the volume of furnaces were applied. Calculations were performed for two regimes of pulverized coal combustion: the traditional one and using plasma activation of coal combustion. It is shown that the use of plasma-fuel systems (PFS) allows the optimization of the coal combustion process in the combustion chamber. Three-dimensional modeling of a pulverized coal furnace equipped with a PTS allows one to determine the optimal PTS layout on boilers of thermal power plants.
